Abstract (en)

[origin: WO2010068613A1] An electric cam phaser (ECP) for a camshaft of an internal combustion engine includes an axial flux electric machine (13) which is axially integrated with a positive differential gear train (12), and which is capable of providing frictional locking. The differential gear train (12) has three co-axial relatable branches. The first branch is connected to an input shaft (11), the second to the output shaft (14), and the third is integrated with a rotor (24) of the electric machine (13). The third branch is the control branch through which the differential gear train (12) can be unlocked from a neutral or "locked" mode of operation during phase adjustment by applying either a resistive torque in a second mode of operation, or a driving torque in a third mode of operation, though the electric machine (13) to the control branch.
